ISPs (StarHub, SingTel, M1) use rolling IP addresses. So even if you haven’t voted, you can be locked out of voting because your current IP address has been used to vote by somebody else. You need to wait for your ISP to give you an unused IP address, or you have to find another connection.

You can vote for up to 15 people at one time. You have to use up all your votes at one go. Voting ends at midnight, Dec 31, 2016.
